Abstract:
A jumper is for an electrical switching apparatus having a plurality of poles. Each of the poles comprises a terminal. The terminal of a first one of the poles is proximate the terminal of a second one of the poles. The jumper includes a jumper member having an attachment portion and a heat sink portion. The attachment portion is structured to electrically connect the terminal of the first one of the poles to the terminal of the second one of the poles. The heat sink portion includes a plurality of spaced apart heat transfer members that are arranged in a plurality of rows and a plurality of columns.
Abstract:
An operating handle interface assembly is for an electrical system. The electrical system includes an enclosure having an interior and an exterior, and a plurality of electrical switching apparatus disposed within the interior. Each of the electrical switching apparatus includes an operating handle. The operating handle interface assembly includes a linking assembly structured to interconnect the operating handles of a plurality of the electrical switching apparatus. An elongated shaft includes opposing first and second ends. The first end cooperates with one of the operating handles of one of the electrical switching apparatus. The second end is disposed on the exterior of the enclosure. A handle attachment is coupled to the second end of the elongated shaft on the exterior of the enclosure. The handle attachment is operable among a plurality of positions to correspondingly operate the operating handles of all of the interconnected electrical switching apparatus.
Abstract:
An improved circuit interrupter assembly provides enablement of an interlock feature for a circuit interrupter situated within a cabinet having an external handle for switching the circuit interrupter between ON and OFF conditions when the cabinet door is closed. The improved circuit interrupter assembly includes a motion transfer apparatus that provides such enablement of the interlock feature for cabinets of any of a variety of depths. The motion transfer apparatus includes a Bowden cable that extends between a first retention assembly situated at the door of the cabinet and a second retention assembly situated at the interlock feature of the circuit interrupter. The Bowden cable has a biased drive cable that extends between a pair of elements and which thus transfers the motion of the cabinet door in its closed position to enable cooperation with the interlock.
Abstract:
A lever assembly is for an operating mechanism of an electrical switching apparatus. The electrical switching apparatus includes a number of pairs of separable contacts structured to move from a CLOSED position to a TRIPPED OPEN position in response to a trip condition. The operating mechanism has an enclosure member and a number of biasing elements coupled to the enclosure member. The biasing elements are structured to move the separable contacts from the CLOSED position to the TRIPPED OPEN position. The lever assembly includes a lever member structured to engage the enclosure member, and a component located on the lever member. The component is structured to extend through each of the biasing elements in order to lengthen each of the biasing elements when the separable contacts are in the CLOSED position.
Abstract:
A guard assembly is for an electrical enclosure. The electrical enclosure includes a housing, an electrical switching apparatus, and a handle. The guard assembly includes: a shaft including a first end and a second end, the first end being structured to be coupled to the handle, the second end being structured to be coupled to the electrical switching apparatus; and a sleeve assembly structured to move between a retracted position and an extended position, the sleeve assembly including a sleeve member, the sleeve member including: a base located proximate the first end of the shaft, and a cover portion extending from the base toward the second end of the shaft, the shaft extending at least partially through the cover portion. Responsive to the sleeve assembly moving from the retracted position toward the extended position, the sleeve member moves away from the second end of the shaft.
